You are required to give somebody exactly 6 pence in two coins, one of which must not be a 5p piece (or exactly 6cents in two coins, one of which must not be a nickel, if you prefer ) ) How do you do it?

UK coinage - 1p, 2p, 5p, 10p, 20p, 50p, £1, £2

US coinage - 1c, 5c, 10c, 25c

I will post the answer once people have had chance to have a go themselves
